    2023-08-10 v3.7.0
    
      This release includes new codec interfaces, compression efficiency and
      perceptual improvements, speedup and memory optimizations and many bug fixes.
      This release is ABI compatible with the last release.
      - New Features
        * New codec controls:
          * AV1E_SET_QUANTIZER_ONE_PASS: Set quantizer for each frame.
          * AV1E_ENABLE_RATE_GUIDE_DELTAQ: enable the rate distribution guided delta
            quantization in all intra mode. The "enable-rate-guide-deltaq" option is
            added for this control.
          * AV1E_SET_RATE_DISTRIBUTION_INFO: set the input file for rate
            distribution used in all intra mode. The "rate-distribution-info" option
            is added for this control.
          * AV1E_GET_LUMA_CDEF_STRENGTH
          * AV1E_SET_BITRATE_ONE_PASS_CBR
        * AOM_SCALING_MODE is extended to include 2/3 and 1/3 scaling.
        * aom_tune_metric is extended to include AOM_TUNE_VMAF_SALIENCY_MAP.
          The "tune" option is extended to include "vmaf_saliency_map".
        * SVC example encoder svc_encoder_rtc is able to use the rate control
          library.
        * Loopfilter level and CDEF filter level is supported by RTC rate control
          library.
        * New speed (--cpu-used) 11, intended for RTC screen sharing, added for
          faster encoding with ~3% bdrate loss with 16% IC (instruction count)
          speedup compared to speed 10.
      - Compression Efficiency Improvements

            * 2 temporal layers on low resolutions: 13-15% BDrate gain
            * 3 temporal layers on VGA/HD: 3-4% BDrate gain
      - Perceptual Quality Improvements
        * Fixed multiple block and color artifacts for RTC screen content by
          * Incorporating color into RD cost for IDTX
